SPECIFICATION forming part of Letters Patent No. 524,594, dated August14, 1894.

Application led November 15, 1 89S. Serial No. 491,022. (No model.)

`To @ZZ whom it may concern:

Be it known that I, ALBERT IsKE, a citizen of the United States,residing at Lancaster', in the county of Lancaster and State ofPennsylvania, have invented certain new and useful Improvements inLatches; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to improvements in a closet or door-latch of thatclass in which a hook, a spring, and a rod are so arranged, combined andsecured in place that the hook will engage a fixed catch, the springhold it engaged, and the rod open the same.

The obj ect of the invention is the construction of a simple and eectivelatch specially designed for use in holding a cupboard or closet doorclosed, and that may be readily disengaged from its catch by the samepull, upon the knob or handle, which is used to open said door. Latchesfor this purpose, constructed after the slide-bolt pattern, and acupboard-catch, patented September 21, 1886, No. 349,671, are well knownto the trade, but in which a turn or push on the knob or handle isrequired to release the door, and a pull thereon to open the same, whilein this invention these two functions are performed at one operation, asimple pnll upon a knob orhandle.

The purposes of the invention are'attained by the mechanism illustratedin the accompanying drawings, in which similar letters of referencedesignate like parts throughout the several views.

Figure 1l is a front elevation of a hinged closet door showing a latchembodying the elements of the invention in position; Fig. 2, a view,from above, of the portion below the line o; m in Fig. 1; Fig. 3, aview, from the right, of the portion to the left of the line y y in Fig.1; Fig. 4, an inside elevation of a portion of Fig. 1, showing the latchand catch in position, and Fig. 5, a detached plan of the latch frame,the supporting plate appearing in horizontal section.

The latch frame (Fig. 5) consists of a supporting plate A having anoutwardly projecting dome A', and an inwardly projecting arm A2, allintegrally made as one casting. The

dome is made hollow to form a recess a to receive an end of a coiledspring, and in its center is an orifice a to permit the passage of theactuating rod; the arm is made hollow above and below to reduce weight,and in its inner end is a vertical U-cut forming two prongs a2 a2provided with a horizontal pivot pin a3 for pivoting thereto thelatch-hook; and the plate is provided with orifices a4 through whichscrews a5 serve to secure itin place (Figs. 1, 2 and 3).

The latch-hook is an angle lever B, somewhat Llshaped,having two arms band b', the former perpendicularly, and the latter horizontally,disposed, and it is pivoted, through the angle, between the prongs a2,to the forward end of the arm A2 (Figs.2 and 3). The arm b', having aprescribed length, has its forward end downwardly and rearwardly slopingso as to move easily up the forward edge of a xed catch-hook yet to bedescribed, and its under edge provided with a hooknotch h2, slightlyunder-cut, to engage said catch-hook; and the arm b, considerablyshorter than the arm b', which it must be to lift said arm b quickly,has its upper end, a little forward of the vertical center line of thelatch pivot, provided with an orifice b3 to pivotally receive aprojecting pin from the side of the forward end of the actuating rod yetto be described.

Extending through the orificea of the having its inner endo dattened onone side to bear against the side of the vertical leverarm b, while arounded pin c projecting from said fiat side and passing through theorifice bof the arm serves to pivot said rod-end to said lever-arm; onthe body of the rod is placed a coiled spring C', having one end withinthe recess a of the dome resting against its wall, and the other end,against pins or lugs c2 projecting from the sides of the rod, theresiliency of the spring serving to keep said rod pressed inward; and,the outer end of the rod is provided with a handle or knob c3, pressingagainst the dome to stop the inward action of the spring, to withdrawthe rod, to disengage the latch, and to open the door.

D designates a hook-catch, so placed and ICQ secured inposition tothebody, or a she1f',ot` L a cupboard or closet, so that it may bereadilyengaged by the latch-hook when the door or portion havingthe attachedlatch is closed.

Now the several parts having been placed in the several positionsindicated in the drawings, and secured in place, an inspection of Fig. 3clearly shows: first, that the spring C acting inward on the rod willkeep the latch in engagement with the catch and the door,

or portion, securely closed; second, that a pully on the knob c3, in thedirection of the arrow l, will lift the latch-hookA in thedirec-tionlrot the arrow 2 from the catch, when said dooro'r portion bythe same pull, continued, will be l readily opened.

Having now` described the invention and set forth the manner in whichitis performed, what I do consider new, and desire to secure by'LettersPatent, is-

The herein described latch comprising: the

`iplateA with the domeA having the recess a and thecentral orifice a',and the arm A2 with the two inner end prongs a2 and a2 having thehorizontal pivot pin a; the angle 1ever B with the arms b and b havingthe hooknotch b2 and the pivot-ori tice b3; the actuating rod C with theilat inner end side having the pivot-pin c', the side projecting pins c2and c2, and the outer end knob c3, and the spring C; and the hook-catchD,-ali arranged, coinbined, and secured in position as shown and for thepurpose hereinbefore set forth.

In testimony whereof I aix my signature in presence of two witnesses.

ALBERT ISKE.
